Question

What are the center and radius of the circle with equation (−)+(−)=?Open x minus 4 close squared . Plus . Open y minus 9 close squared . Equals , 1 question mark

Answer 1

Answer:

Center and radius of the circle of the  equation  ${(x - 4)^{2} + (y - 9)^{2} = 1$

center = ( 4,9)         Radius = 1

Step-by-step explanation:

Given -

Equation of circle is  $(x - 4)^{2} + (y - 9)^{2} = 1$

The equation of circle is  represented by

   $\boldsymbol{\mathbf{(x - a)^{2} + (y - b)^{2} = r^{2}}}$

where a and b are center of circle and radius r

Comparing these equation

then a = 4  and b = 9    and r = 1
